Well, I think the greatest challenge is really time and space. We have 1,200 employees worldwide. We work in 150 countries. In any given time, there are some places you can't go to. I've just come back from a couple of years in the United Kingdom, where I was called another great title, “director of outer area” in the United Kingdom, which basically consisted of all the war graves in eastern Africa, the Indian subcontinent, the Middle East, the Far East, and the Caribbean. I went to Iraq. There are 40,000 people on a memorial in Iraq. We have several war cemeteries there.
In the U.K., we were under some pressure, as it was felt that some progress was being made in Iraq, to go and do something about these graves. I went to Baghdad. I went to Fallujah, and we did a little bit of very rudimentary maintenance to make sure that at least the outline of these cemeteries were still there. Obviously we're quite aware of optics and everything else. We're not going to go into a war-torn country, rebuild the walls, and put in irrigation and everything else while the people just outside of it are starving.
But wars, disease—if you can think of the kind of work that you put into making sure that grubs don't come on your own lawns wherever you happen to live, you can imagine what we do around the world. It's natural hazards like that, and aging structures. I mean, many of our structures were built by the pre-eminent architects of the day just after the First World War; the Menin Gate for example, if you've ever been there, and Thiepval, which is the largest one in the world, on the Somme—they require constant maintenance.
